Hot-melt adhesive, and wood composite structures produced therewith

ABSTRACT

a hot-melt adhesive is shown which contains 75 to 99 parts by weight of depolymerized scrap rubber. From 1 to 25 parts by weight of an additive are included. The additive can include an elastomer, a resin, or a filler, or any combination thereof. The depolymerized scrap rubber is produced by heating solid scrap rubber in contact with a hydrocarbon liquid at 400° to 800° F. for 0.1 to 50 hours. 
     In use, the adhesive is heated and combined with two or more wood elements. When the combination cools, a composite wood structure is obtained.
